Abstract

<P>PROBLEM TO BE SOLVED: To provide multilayer roll goods which can be handled and processed without adversely affecting the flow area of the roll goods. <P>SOLUTION: A laminated article 20 includes a first web 42 of material of a first width W. A second web 44 of material has a second width substantially equal to the first width W. The second web 44 is coextensive with the first web 42. The second web 44 is laminated to the first web 42 at lateral portions 22, 24. A permeable unlaminated portion 46 extends transversely between the laminated lateral portions 22, 24. The widths E1, E2 of the laminated lateral portions 22, 24 are each less than the half of the first width W. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、広義にはラミネートシート素材に関する。詳しくは、本発明は縁で貼り合わせたロール物品に関する。   The present invention relates generally to a laminate sheet material. Specifically, the present invention relates to a roll article bonded with an edge.

ロール物品は公知である。ロール物品は、通例、それ自体で巻き取るか或いは円筒形の芯に巻き取った比較的長い材料シートとしてユーザに提供される。最終製品又は中間製品への加工中に、ロール物品のシート材料は巻き戻され、以降のプロセスで必要とされる長さに切断される。   Roll articles are known. Roll articles are typically provided to the user as a relatively long sheet of material that is wound up on its own or wound around a cylindrical core. During processing into a final or intermediate product, the sheet material of the roll article is unwound and cut to the length required in subsequent processes.

かかる最終製品の一例は流体用のカートリッジフィルタである。カートリッジフィルタはプリーツフィルタ媒体エレメントを含むことがある。フィルタ媒体は、２以上の材料層のラミネートであることがある。材料層の１つは延伸ポリテトラフルオロエチレン（ｅＰＴＦＥ）膜で、これを布基材（不織布又は織布）に貼り合わせたものがある。ｅＰＴＦＥ膜は流体濾過用途で多くの利点をもたらし、かかる用途での使用に極めて望ましい。   An example of such a final product is a fluid cartridge filter. The cartridge filter may include a pleated filter media element. The filter media may be a laminate of two or more material layers. One of the material layers is an expanded polytetrafluoroethylene (ePTFE) film, which is bonded to a cloth substrate (nonwoven fabric or woven fabric). ePTFE membranes offer many advantages in fluid filtration applications and are highly desirable for use in such applications.

ｅＰＴＦＥ膜は比較的脆く、取扱い及び加工が困難である。取扱い及び加工を容易にするため、一般にラミネートが必要とされる。しかし、貼合せによって利用可能な流路面積が通例減少してしまう。   ePTFE membranes are relatively fragile and difficult to handle and process. Laminates are generally required for ease of handling and processing. However, the available channel area is usually reduced by the bonding.

そこで、ロール物品の流路面積に有害な影響を与えずに取扱い及び加工できる多層ロール物品を提供する必要性が存在する。   Thus, there is a need to provide a multilayer roll article that can be handled and processed without adversely affecting the flow path area of the roll article.

一態様に係るラミネート物品は、第１の幅を有する第１の材料ウェブを含む。第２の材料ウェブは第１の幅と実質的に等しい第２の幅を有する。第２のウェブは第１のウェブと同じ範囲に延在する。第２のウェブは、側部で第１のウェブに貼り合わされる。貼り合わせた側部の横に透過性の非貼合せ部が延在している。貼り合わせた側部の幅は第１の幅の１／２未満である。   A laminate article according to one aspect includes a first material web having a first width. The second material web has a second width that is substantially equal to the first width. The second web extends in the same range as the first web. The second web is bonded to the first web at the side. A transparent non-bonding portion extends beside the bonded side portions.

濾過媒体は、大抵の場合、延伸ポリテトラフルオロエチレン（ｅＰＴＦＥ）膜のような１以上の材料層を含んでいるが、これは比較的脆く、下流の加工プロセスでの取扱い及び加工が困難である。かかる濾過媒体を使用する製品の一例はカートリッジフィルタである。ｅＰＴＦＥ膜は、不織布又は織布基材に貼り合わされる。しかし、貼合せ法は濾過媒体の流体透過性を低下させてしまう。今回、下流プロセスで容易に取り扱うことができるラミネートの流体透過性を最大限にするため、少なくとも一方の外側縁を貼り合わせた多層ロール物品製品を開発した。ロール物品の残部は、その部分を通して最大流量又は流体透過性を得るために貼り合わせていない。   Filtration media often includes one or more layers of material such as expanded polytetrafluoroethylene (ePTFE) membranes, which are relatively brittle and difficult to handle and process in downstream processing processes. . An example of a product that uses such a filtration medium is a cartridge filter. The ePTFE membrane is bonded to a nonwoven fabric or a woven fabric substrate. However, the laminating method reduces the fluid permeability of the filtration medium. In order to maximize the fluid permeability of laminates that can be easily handled in downstream processes, we have developed a multilayer roll article product with at least one outer edge bonded. The remainder of the roll article is not bonded to obtain maximum flow rate or fluid permeability through that portion.

本発明の一態様では、少なくとも一方の縁２２又は２４、好ましくは最も外側の両縁２２及び２４で貼り合わせた多層ラミネート物品２０（図１）を提供する。かかるラミネート物品２０は、最も外側の両縁２２及び２４の間に位置する比較的大きな流路面積を有する濾過媒体としての容易に取扱い及び加工することができる。   In one aspect of the invention, a multilayer laminate article 20 (FIG. 1) is provided that is bonded at least one edge 22 or 24, preferably the outermost edges 22 and 24. Such a laminate article 20 can be easily handled and processed as a filtration medium having a relatively large flow area located between the outermost edges 22 and 24.

ラミネート物品２０は、第１の幅Ｗを有する第１の材料層又はウェブ４２を含む。ラミネート物品２０は、第１の幅Ｗと実質的に等しい第２の幅を有する第２の材料層又はウェブ４４も含む。第１のウェブ４２は第２のウェブ４４上に位置し、第２のウェブと同じ範囲に延在する。第２のウェブ４４は、好ましくは両側の側部又は最も外側の縁２２及び２４で第１のウェブ４２に連続的に貼り合わされる。明らかであろうが、貼合せ縁部２２及び２４は非連続的な方法でも形成できる。貼り合わせた側部の間には透過性の非貼合せ部４６が延在している。２枚のウェブ４２及び４４のみで構成されたラミネート物品２０を図示したが、ラミネート物品に適宜任意の数のウェブ又は層を組み込むことができるのは自明であろう。   The laminate article 20 includes a first material layer or web 42 having a first width W. The laminate article 20 also includes a second material layer or web 44 having a second width substantially equal to the first width W. The first web 42 is located on the second web 44 and extends in the same range as the second web. The second web 44 is preferably continuously bonded to the first web 42 at either side or outermost edges 22 and 24. As will be apparent, the bonded edges 22 and 24 can also be formed in a discontinuous manner. A transparent non-bonding portion 46 extends between the bonded side portions. While a laminated article 20 composed of only two webs 42 and 44 is shown, it will be apparent that any number of webs or layers can be incorporated into the laminated article as appropriate.

「ウェブ」、「ラミネート物品」及び「ロール物品」という用語は、幅Ｗと直角の方向に延びる長さＬを有するシート材料を意味する。長さＬは幅Ｗよりも実質的に長い。例えば、幅Ｗ１０．５〜２６インチ、長さＬ１００ヤード以上としてもよい。   The terms “web”, “laminate article” and “roll article” mean a sheet material having a length L extending in a direction perpendicular to the width W. The length L is substantially longer than the width W. For example, it is good also as width W10.5-26 inches and length L100 yards or more.

ラミネート物品２０の第１のウェブ４２は、濾過基材に適した任意の材料（例えば、メルトブローエチレンクロロトリフルオロエチレン不織布）から製造される。使用できる他の好適な材料の例は、スパンボンド、スパンレース、ドライレイド又はサーマルボンド熱可塑性樹脂のような不織布、例えばメルトブロー法で得られるポリプロピレン、ポリエステル、ポリエチレン又はナイロンなどである。ラミネート物品２０は、第１の材料ウェブ４２と第２の材料ウェブ４４をラミネート物品の全長Ｌにわたり両側縁部２２及び２４で貼り合わせたものである。貼合せ縁部２２及び２４は、好ましくは実質的にラミネート物品２０の全長Ｌにわたって連続的に延在している。   The first web 42 of the laminate article 20 is made from any material suitable for a filtration substrate (eg, meltblown ethylene chlorotrifluoroethylene nonwoven). Examples of other suitable materials that can be used are non-woven fabrics such as spunbond, spunlace, dry laid or thermal bond thermoplastics, such as polypropylene, polyester, polyethylene or nylon obtained by meltblowing. The laminate article 20 is obtained by laminating a first material web 42 and a second material web 44 at both side edges 22 and 24 over the entire length L of the laminate article. The lamination edges 22 and 24 preferably extend continuously substantially over the entire length L of the laminate article 20.

好ましくは貼合せは図２に示すように熱圧着法で行われるが、超音波、ＲＦ、レーザ及び接着剤のような任意の適当な貼合せ法を使用し得る。ラミネート物品２０は、第１の材料ウェブ４２と第２の材料ウェブ４４を、各貼合せウェブのそれぞれの最も外側の側縁で連続的に貼り合わせたものである。貼り合わせた側部２２及び２４のそれぞれの幅Ｅ１及びＥ２は第１の幅Ｗの１／２未満、好ましくは第１の幅の２５％未満であり、さらに好ましくは第１の幅の約１５％未満である。非貼合せ部４６は比較的高い流量又は透過性を有し、濾過媒体としての使用に非常に適している。非貼合せ部４６は、好適にはフィルタカートリッジ用のプリーツ濾過媒体に形成できる。   Preferably, the bonding is performed by thermocompression bonding as shown in FIG. 2, but any suitable bonding method such as ultrasonic, RF, laser and adhesive may be used. The laminate article 20 is obtained by continuously laminating a first material web 42 and a second material web 44 at each outermost side edge of each laminating web. The respective widths E1 and E2 of the bonded side portions 22 and 24 are less than ½ of the first width W, preferably less than 25% of the first width, and more preferably about 15 of the first width. %. The non-bonding portion 46 has a relatively high flow rate or permeability and is very suitable for use as a filtration medium. The non-bonding part 46 can be preferably formed in a pleated filtration medium for a filter cartridge.

ラミネート物品２０の第２のウェブ４４は、好ましくはミクロ多孔質膜の形態である。ミクロ多孔質膜は、好ましくは延伸ポリテトラフルオロエチレン（ｅＰＴＦＥ）のような材料から製造される。第２のウェブ４４は、任意の適当な材料、例えばポリテトラフルオロエチレン、ポリオレフィン、ポリアミド、ポリエステル、ポリスルホン、ポリエーテル、アクリル系及びメタクリル系ポリマー、ポリスチレン、ポリウレタン、ポリプロピレン、ポリエチレン、ポリフェニレンスルホン並びにこれらの混合物から製造し得る。   The second web 44 of the laminate article 20 is preferably in the form of a microporous membrane. The microporous membrane is preferably made from a material such as expanded polytetrafluoroethylene (ePTFE). The second web 44 may be any suitable material such as polytetrafluoroethylene, polyolefin, polyamide, polyester, polysulfone, polyether, acrylic and methacrylic polymers, polystyrene, polyurethane, polypropylene, polyethylene, polyphenylene sulfone and the like. It can be produced from a mixture.

ｅＰＴＦＥ膜は、通例、公知のように複数のノードがフィブリルで相互に連結してミクロポーラスな格子型構造を形成している。ミクロ多孔質ｅＰＴＦＥ膜の細孔に関する好適な平均孔径は０．００１〜１０μｍ、好ましくは０．００５〜５．０μｍの範囲内にある。通例、ミクロ多孔質膜の多孔度（膜の体積に占める開放空間の百分率）は約５０〜約９８％である。大抵の場合、多くの濾過用途に適するラミネート物品２０のミクロ多孔質膜の多孔度は約７０〜約９５％、好ましくは約８０〜約９５％の範囲内にある。ミクロ多孔質膜は、「官能化」によって親水性とし、液体濾過用途に極めて適したものとすることができる。   In the ePTFE membrane, as is generally known, a plurality of nodes are interconnected by fibrils to form a microporous lattice structure. A suitable average pore size for the pores of the microporous ePTFE membrane is in the range of 0.001 to 10 μm, preferably 0.005 to 5.0 μm. Typically, the porosity of a microporous membrane (percentage of open space in the membrane volume) is about 50 to about 98%. In most cases, the porosity of the microporous membrane of laminate article 20 suitable for many filtration applications is in the range of about 70 to about 95%, preferably about 80 to about 95%. The microporous membrane can be rendered hydrophilic by “functionalization” and can be very suitable for liquid filtration applications.

一態様に係るラミネート物品２０を、メルトブロー基材からなる第１のウェブ４２とｅＰＴＦＥ膜からなる第２のウェブ４４から製造した。メルトブロー基材は、Ｍｏｎａｄｎｏｃｋ社からＨａｌａｒ（登録商標）という商品名で市販されている１００ｇ／ｃｍ2のエチレンクロロトリフルオロエチレン（ＥＣＴＦＥ）不織布から製造した。第２のウェブ４４のｅＰＴＦＥ膜は０．２μｍの平均孔径を有していた。ラミネート物品２０は、液体フィルタカートリッジへと加工するのに非常に適している。 A laminate article 20 according to one embodiment was manufactured from a first web 42 made of a melt blown substrate and a second web 44 made of an ePTFE membrane. The meltblown substrate was made from a 100 g / cm 2 ethylene chlorotrifluoroethylene (ECTFE) nonwoven fabric commercially available from Monadnock under the trade name Halar®. The ePTFE membrane of the second web 44 had an average pore size of 0.2 μm. The laminate article 20 is very suitable for processing into a liquid filter cartridge.

ラミネート物品２０は、所望の完成品サイズに応じて約１０．５〜約１２インチの幅Ｗを有し得る。貼合せ縁部２２及び２４の幅Ｅ１及びＥ２は、好ましくは約１／２インチ〜約１インチの範囲内にあるが、どのような適当な幅であってもよい。第２のウェブ４４のｅＰＴＦＥ膜は、縁部２２及び２４で第１のウェブ４２のメルトブロー基材に連続的に貼り合わされる。かくして、例えばラミネート物品をフィルタカートリッジ用のプリーツ濾過媒体へと加工する作業で加工できる構造を有しつつ、非貼合せ部４６を通してラミネート物品２０の最大流体透過性が得られる。   Laminate article 20 may have a width W of about 10.5 to about 12 inches, depending on the desired finished product size. The widths E1 and E2 of the laminating edges 22 and 24 are preferably in the range of about 1/2 inch to about 1 inch, but can be any suitable width. The ePTFE membrane of the second web 44 is continuously bonded to the meltblown substrate of the first web 42 at the edges 22 and 24. Thus, for example, the maximum fluid permeability of the laminated article 20 can be obtained through the non-bonding portion 46 while having a structure that can be processed by processing the laminated article into a pleated filtration medium for a filter cartridge.

図３に示す態様では、ラミネート物品２０ａは第１のウェブ４２ａのメルトブロー基材を有する。第２のウェブ４４ａのｅＰＴＦＥ膜は、貼合せ縁部２２ａで第１のウェブ４２ａのメルトブロー基材に接着剤で連続的に貼り合わされる。最大流路面積を得るため、縁部２２ａの横方向内側にはやはり透過性の非貼合せ部４６ａが延在している。ラミネート物品２０ａの縁部２２ａのみが接着剤で貼り合わせているように図示されているが、縁部２４ａ（図示せず）も接着剤で貼合せできることは自明であろう。ラミネート物品２０ａは約１０．５〜約１２インチの幅Ｗを有し得る。貼合せ縁部２２ａ及び２４ａの幅Ｅ１及びＥ２は、好ましくは約１／２インチ〜１インチであるが、どのような適当な幅であってもよい。   In the embodiment shown in FIG. 3, the laminate article 20a has a melt blown substrate of the first web 42a. The ePTFE film of the second web 44a is continuously bonded with an adhesive to the melt blown base material of the first web 42a at the bonding edge 22a. In order to obtain the maximum channel area, a non-bonding portion 46a that is permeable also extends on the inner side in the lateral direction of the edge portion 22a.

An outer portion 62 is present. In order to obtain the maximum channel area, a non-bonding portion 46b that is permeable also extends on the inner side in the lateral direction of the edge portion 22b. Although only the edge portion 22b is illustrated as being bonded, it is obvious that the edge portion 24b (not illustrated) can also be bonded while providing a relatively small non-bonded outer portion on the laterally outer side. Laminate article 20b may have a width W of about 10.5 to about 12 inches. The widths E1 and E2 of the laminating edges 22b and 24b are preferably about 0.375 to about 0.75 inches, but can be any suitable width.

ラミネート物品２０ｄは、ラミネート物品の全長Ｌにわたって延在して非貼合せ部４６ｄを分断又は分割する中間貼合せ部２６ｄを含む。中間貼合せ部２６ｄは、好ましくは第１のウェブ４２ｄと第２のウェブ４４ｄとの間に非貼合せ部と貼合せ部とが交互に配列されている。中間貼合せ部２６ｄは、例えばスポット溶着又は不連続ストリップの形態の貼合せなど、適当な貼合せ法で形成できる。ラミネート物品２０ｄの中心線に対して追加の中間貼合せ部２６ｄを設けると、比較的幅広いロール物品を容易に取扱うことができるようになる。中間貼合せ部２６ｄはラミネート物品２０ｄの中心線に沿って配置できるが、これはラミネート物品をスリットするための位置決め用又は案内用インジケータとなり得るし、或いはラミネート物品のプロセス取扱い時の安定性を得るための増強結合機構としても役立ち得る。   The laminate article 20d includes an intermediate bonding portion 26d that extends over the entire length L of the laminate article and divides or divides the non-bonding portion 46d. In the intermediate laminating portion 26d, preferably, the non-laminating portion and the laminating portion are alternately arranged between the first web 42d and the second web 44d. The intermediate bonding part 26d can be formed by an appropriate bonding method such as spot welding or bonding in the form of a discontinuous strip. Providing the additional intermediate laminating portion 26d with respect to the center line of the laminated article 20d makes it possible to easily handle a relatively wide roll article. The intermediate laminating portion 26d can be arranged along the center line of the laminated article 20d, but this can be a positioning or guiding indicator for slitting the laminated article, or to obtain stability during process handling of the laminated article. It can also serve as an enhanced binding mechanism for.
